`Application filed January 11, 1924. Serial No. 685,511.

` description of the same, reference being had to the accompanying drawings, and'to the numerals of reference marked thereon which form a part ofthis specification.

"This invention relates to a shoring device adapted for sustaining the outer Wall of a building or the like during the `construction thereof;

It is an object of this nvention to provide a simple shoringdevice thatmay be easily` adjusted by common means and that Will readily sustain the weight of the wallwith out yielding.

V The invention comprisesthe novcl structure and combinations hereinafter described and more particularly polnted out and de- `fined in the appende d'claim.

n' the accompanying drawings which i1 lustrate a preferred embodiment of thisinention and` in which similar reference numerals refer to similar features in the different views Figure 1 is an elevational View of my shoring device supporting the form for a concrcte wall shown in section. V

Figure 2 is an enlarged vertical sectional view through the shoringdevice.

i Figure 3 is an enlarged `Sectionahview upon the line 3+3 of Flgure l with parts 111" elevation.

the numcral `1 Referring to the drawing, represents the/base of the shoring device having an upwardly extending tubular Standard 2 through which a hollow rod 3 may pass. A' split clalnping collar 4 rests upon'the top of the tube 2 and supports the hollow rod by being .firm ly clamped thereto.

A U shaped bracket having a depending.

lug (5 extending into the uppenend ot' `the hollow rod 3 1s aiXed thereto by a' pln or bolt extending through the said rod andlug A supporting beam 7is secured intermediate its ends in the U bracket 5;

The ends of this beam are connected by inclined struts'or braces 8 and 9 with a'lower' supporting block 10 provided with a central aperture' for receiving the hollow rocl 3 and resting upon the split collar 4.

A `p'lurality of short pipe sections 11 eX' tend from the collar 4 to the bracket 5 and forma Support` for the lat-ter with respect to the Collar 4. Pipe sections may be readly added or removed as is obvious for any particular height that it is desiredto port theform for the wall collar las is obvious. s

A plurality otsuch Shoring devi'ces'are adaptedto be spaced at regular intervals for supporting a form `for a wall into' Which concrete may be poured. In Figure 1, such a 'form is shown as is "indicated by the i referencel. The outenside 12 of this form is 'braced by 'a diagonal' strut 13 attached at its lower end to the beam 7 and bearing at its upper end against a longitudinally extending beam 14; positioned against the outer side 12 'of the form.

I am' aware that many changes may be made, andnumerous details of construction' t P the rod' 3 being raised or lowered by unclampingthe split may be varied through a Wide range without departlng from the pr nc ples of this in 2 vention, and .I `therefore do not purpose limiting the patent grantedhereon,otherwise than necessitated by the prior art; l

I claim as"`my invention; i

ln a'shoring device, a base, a hollow tube eXtending' from said base, a clamping oollar resting upon said tube, a rod extending through s aid clamping co11ar,'a bracket'attachjed to the "upper end of said rod, a beam plpesections surrounding said rod and eX- tending betweensaidcollar and bracket, a

blocksupported upon saidcollar and braces connecting said beam and block.
